Accessing multiple EJBs on different JBoss AS instances

[dkrizic]

Hello,

I would to access two independent EJBs on two different JBoss instances, each is secured with a uniquely named SecurityDomain. Here is my authentication configuration:

darko {
 org.jboss.security.ClientLoginModule required debug=true;
};

jochen {
 org.jboss.security.ClientLoginModule required debug=true;
};

Then I login to the first one (login 1)

 log.info("LoginContext [darko]");
 UsernamePasswordHandler uph = new UsernamePasswordHandler("darko",
 "test");
 LoginContext loginContext = new LoginContext("darko", uph);
 loginContext.login();

Then I access the session bean (access 1):

 log.info("PersonService [darko]");
 PersonService ps = (PersonService) getService(PersonService.REMOTE_NAME);
 Person p = new Person(null, "Darko", "Krizic");
 p = ps.add(p);
 assertNotNull(p.getId());
 assertEquals(1, ps.listPersons().size());
 ps.update(p);
 ps.remove(p.getId());
 assertEquals(0, ps.listPersons().size());

Then I login to the second JBoss instance (login 2)

 log.info("LoginContext [jochen]");
 UsernamePasswordHandler uph2 = new UsernamePasswordHandler(
 "jochen", "test2");
 LoginContext loginContext2 = new LoginContext("jochen", uph2);
 loginContext2.login();

and then I access the second (technically identical) session bean (access 2)::

 log.info("PersonService [jochen]");
 PersonService ps2 = (PersonService) getService2(PersonService.REMOTE_NAME);
 Person p2 = new Person(null, "Jochen", "Grau");
 p2 = ps2.add(p2);
 assertNotNull(p2.getId());
 assertEquals(1, ps2.listPersons().size());
 ps2.update(p2);
 ps2.remove(p2.getId());
 assertEquals(0, ps2.listPersons().size());

This works so far, but when I change the order from

login 1
access 1
login 2
access 2

to

login 1
login 2
access 1
access 2

The code does not work anymore. Obviously the login module is not able to handle this. What could I do? Would a separation in different classloaders work?

Obviously it would not work. No, it has nothing to do with ClassLoaders. Tell us what you are trying to do ?

You want to know, why I want this to work? The reason is simple: I want to integrate multiple applications clients under one single Eclipse RCP frontend. Each of those clients are accessing their own backend, but since they are in Eclipse RCP, they are all running under the same JVM.

Regards,

Darko

login 1
access 1
login 2
access 2

Why this order is not enough ?

Hi Darko,

to make this work, you need to start parallel threads and you also have to add another option to the login.conf:

multi-threaded=true

HTH + best regards,
